The design we have decided upon to complete our task is broken into multiple components. The first portion is the making of a dynamo. In order to save some time and money, a small electric motor will be incorporated as the permanent magnets and wire coil, instead creating those components from scratch. However, as the motor is quite small, a gear train will be necessary to connect the wheel of the bike with the motor and to rotate fast enough to generate energy. This gear train and motor will be encased in a 3D printed casing and will be mounted to the front fork of the bicycle.
The second component of the project has multiple sub components. The first of which is the battery system. This conglomerate of circuitry pieces will come together to form a bridge rectifier in order to convert any AC current into DC current. The DC current will then flow into a series of capacitors which will store excess electricity. Finally, a voltage regulator will act as the floodgates, only allowing 5 volts of electricity to flow forth from the capacitors at any given time. A USB port will be attached at the end so that any phone can be plugged in and charged.
The battery system will be housed in the next sub component, the phone box. The purpose of the phone box is to provide a waterproof shell in which the battery system as well as the users phone can be stored while riding and charging. This box will be designed and 3D printed as to mount upon the down tube of the bicycle.
Each of the components are then to be assembled and mounted upon the bike to work as a functioning unit. If the electric motor fails to generate enough electricity, a bottle dynamo will be purchased in order to ensure the project succeeds.
